Button Contacts For Cr2032 Batteries

I run through a bunch of CR2032 batteries every couple of months. I like these because battery life has been good, and I can buy them at a reasonable price through B&H.

Been using these for 10 years for my Fujifilm, Canon and Nikon batteries. Contacts 'up' they're charged, contacts 'down' they're empty. Keeps battery life simple, and (snapped together) they all fit into one lens slot in my bags.

Is well. made. Provides safe storage for carrying batteries while protecting the contacts.

Keeps batteries from moving around in my sac and eliminates the danger of contacts touching each other.

This pouch keeps my batteries safe in my bag, no scratches to battery body or contacts.

Convenient for small DSLR batteries. Safe for air travel as it keeps the contacts covered.

When the charger arrived, I pulled out two of my spare batteries to test it. Before I installed the plates into the charger, I looked at the battery contacts and got worried, but upon closer examination of the batteries, I saw that there were two recessed contacts (as opposed to the primary visible-contacts) which these plates use to charge the batteries. The batteries slipped into the plates firmly, and the plates popped into the charger. I left the charger unplugged at first to make sure that the LCD showed current battery status. Both readouts came up and showed the status of each battery. I plugged the charger in and let it do it's thing. I also purchased three other sets of charging plates for different battery types, but haven't had a chance to try them yet. If all goes as well as it did this time, I can just look for new plates as I get different batteries.

I discovered that I can't operate the PO-12 in my hand since it puts tension on the batteries, bending the battery positive or negative contacts away from the battery. It should be operated on a firm surface. When removing the batteries, keep one finger pushing inwards towards the battery and use a flat head screwdriver to push the other end of the battery inward and upwards. If the contacts do bend, then remove the batteries and gently apply inward pressure to restore them to their original position. That aside, the price and number of sound variations make this synthesizer a buyer's deal.

I really like that these 9 volt batteries have plastic covers for the +/- contacts. This allows me to place spares in my camera bags without needing to find a bag or box to prevent a battery from shorting out.

These are great! I always carry extra batteries for my Fuji camera but have worried about the contacts not being covered. This takes care of that worry. I charge the batteries, but them in here and cease to worry!
